FluxLight

Very easy to buy. Did not test them yet but I think they should have high MTBF

Very fast,,,

We still are receiving the same excellent service and great quality of product, thank you. The FluxLight Products we purchased over the years has yet to fail.

Very impressive low-cost alternative to expensive name brand modules. Plug-n-play ease. Tech support was very friendly and helpful with sorting out a RX/TX polarity issue I encountered during install. FluxLight is top notch!

Every SFP I've purchased from FluxLight works, just like I expect, just like it should. I have been very pleased with their performance and will continue to purchase and recommend them.
